Consider the simple pipe network below. Pipe AB and CF are both 500m long withdiameters of 0.8m and friction factors of 0.015. Branch 1 is 200m long, 0.5m in diameter with a frictionfactor of 0.02. Branch 2 is 300m long, 0.6m in diameter with a friction factor of 0.012. The designdischarge through pipe AB is 3m 3 /s. Determine the following: a) the equivalent pipe length, Leq, of asingle equivalent pipe with a diameter of 1m and friction factor of 0.02, that represents the entire pipenetwork from A to F, b) determine the total head loss from A to F. Ignore minor losses. (Hint: need touse method of equivalent pipes for both series and parallel)

Answer with True (T) or False (F). 1. Relative Roughness may larger than 1. 2. Moddy Diagram used to determine minor losses coefficient. 3. Froud Number may use in open channel and pipe. 4. Real power for pump larger than design power. 5. In pipe series system discharges are equal. 6. In parallel pipe system head losses are not equal. 7. You could use Bernoulli equation between two tanks at branched pipe system. 8. Top width for trapezoidal channel = base width+ 2*(water depth* longitudinal slope). 9. Specific volume in FLT system FT²/L² 10. Kinematic viscosity in MLT and FLT systems are equal.
A dam includes a sheet pile "cut off" wall near the toe, installed to 7 ft below the groundline. Water seepage is assumed to be at steady state at this time step shown. At this time, the depth of the upstream pond (headwater) is 5 feet. The groundwater is at the same level as the ground on the downstream/tailwater side. The sand stratum thickness, where water is flowing, is 9 ft thick. The permeability of the sand, in the zone of the flow net, is k=42ft/day, the length of the dam (into the page) is 150 ft, and the unit weight of the sand is γsat=128 lb/ft3 (saturated unit weight of the soil). Use γw=62.4 pcf (unit weight of water) for your calculations, where necessary.What is the factor of safety against a quick condition? (use the dimensions given in the problem state to help estimate lengths, where needed)
Q#4 : For the concrete Dam shown in figure, determine the total average seepage for the given permeable strata by drawing Flow Net. The detail dimensions are given on the figure. The head of water on upstream side is 6ft and on downstream side is 1ft. Assume of Nf= 3, Nd= 6 and rectangular flow elements. Use MSpaint or graph paper
